Relays, function relays
The logic relay has different types of relay for wiring in a 
circuit diagram.
You can set the switching behaviour of these relays by 
means of the coil functions and parameters selected.

In order to ensure compatibility with the AC010 devices, 
each CL-LSR/CL-LST and CL-LMR/CL-LMT logically 
supports all relay types internally. If a relay type is not 
supported by the device, the switching state of the 
contacts is always set to zero. The switching states of 
contacts (n/o) and time switches are always logically zero.
This feature enables the same circuit diagram to be used 
on all CL-AC1, CL-AC2, CL-DC1 and CL-DC2 devices. 
Furthermore, you can use outputs that are not physically 
present as markers.
